FIG. 1 is a simplified bock diagram of an exemplary embodiment of the overall system architecture. A system control board 101 preferably contains at least a processor 50, electronic storage 60, and a network interface component 70 (which preferably includes a power button 75). In exemplary embodiments of the present invention, the power button 75 is electrically connected to the system control board 101 such that the system control board 101 may simulate the user physically pressing the power button 75 as will be explained in greater detail herein. For example, but without limitation, the network interface component 70 may be electrically connected to the power button 75 via the power control header on the system control board 101. Similarly, the system control board 101 may be electrically connected to a power supply for the display assembly 200 a such that the system control board 101 may simulate the user physically removing the power supply (i.e., unplugging) and reattaching the power supply (i.e., plugging back in).

A timing and control board (TCON) 102 is preferably in electrical connection with the system control board 101 as well as the electronic display 30. A primary video player 103 a is also preferably in electrical connection with the system control board 101. An optional secondary video player 103 b may also be in electrical connection with the system control board 101. Each video player preferably includes a power button 104 and a power LED 105 (labeled 104 a, 105 a, 104 b, and 105 b, respectively). Similar to the power button 75, the network interface component 70 may be electrically connected to the power button 104 and the power LED 105 as well as the power supply source to the video players 103 a and 103 b by way of the system control board 101 such that the system may simulate physically pressing the power button 104 as well as physically removing the power supply to the video players 103 and reattaching it.

A network operations center device 200 preferably contains at least a processor 51, electronic storage 61, and a network interface component 71 which communicates with the network interface component 70 on the display assembly 200 a. Two other display assemblies 200 b and 200 c are shown in electrical connection with the network operations center device 200, and each would preferably have the same components as shown and described for the display assembly 200 a, but this is not required. In some embodiments however, there could be even more than three display assemblies in electrical connection with the network operations center device.

FIG. 1A is a simplified block diagram of another exemplary embodiment of the overall system architecture. In this embodiment the display assembly 200 d may be similar to that show in FIG. 1, but be comprised of a first display 30 a and a second display 30 b. The first display 30 a may be in electrical connection with a first TCON 102 a and the second display 30 b may be in electrical connection with a second TCON 102 b. The first and second TCONs 102 a and 102 b, respectively, may be in electrical communication with the system control board 101. The video players 103 a and 103 b may each comprise two electrical connections with the system control board 101 such that each video player 103 a and 103 b may control both the first and the second displays 30 a and 30 b.

FIG. 2 is a logical flowchart for operating a first embodiment of the system. In this embodiment, the system begins by applying power to the video player 103 a. The system may next allow time for the display assembly to boot up, such as but not limited to, by use of a timer or counter.

In this embodiment, the system may then monitor the video player 103 a to see if it is communicating, thus indicating normal operation. The system may monitor the video player 103 a by checking for a heartbeat signal, which is periodically generated by the video player 103 a to indicate normal operation or to synchronize other parts of the system. Alternatively, the system may monitor the signal from the power LED 105 to see if it is active. As another alternative, the system may transmit a ping to see if the video player 103 a responds. In still further alternate embodiments, the system may check for status messages that may be periodically sent from the player 103 a to the control board 101. If the video player 103 a is communicating though any of the aforementioned or other means, the system may continue to apply power to the video player 103 a.

If the video player 103 a is not communicating, the system may do one of two things. First, the system may initiate a recovery sequence as described in greater detail in FIG. 9. Second, the system may store a downtime event or failure data at the system control board 101 and optionally transmit the downtime event or failure data to the NOC device 200. In some embodiments, the system may perform both functions when no communication is detected from the player 103 a.

Regardless, if the video player 103 is communicating, the system may return to the beginning of the logic and simply apply power to the video player 103 a while continuing to monitor the signal from the power LED 105 a.

FIG. 3 is a logical flowchart for operating a second embodiment of the system. Here the system begins by driving the display 30 from the primary player 103 a. The system would then check to determine if any failure data or downtime event had been stored for the primary player 103 a and if not, the system continues the normal operations with the primary player 103 a. If any failure data or downtime event had been stored for the primary player 103 a, the system may then switch to drive the display 30 from the secondary player 103 b. For example, but not to serve as a limitation, a failure or downtime event may include no video being shown on the display 30, an unsupported resolution format being received, an unsupported frame rate being received, an error message being received, or the like.

Those having an ordinary level of skill in the arts will recognize that any threshold of amount, frequency, or type of failure data or downtime events may be set such that the system will not switch between the primary player 103 a and the secondary player 103 b until the threshold has been met or exceeded.

FIG. 4 is a logical flowchart for operating a third embodiment of the system. In this embodiment, the system begins with logic similar to that shown and described above with respect to FIG. 3.

Under normal operating conditions, the system may drive the display 30 from the first video player 103 a. However, once the system switches to the secondary player 103 b, the system would preferably check to determine if the second video player 103 b is communicating. If so, the system may continue normal operations with the second video player 103 b. If not, the system may then do one of two things. First, the system may initiate a recovery sequence on the second video player 103 b as previously discussed. Second, or in addition, the system may check to see if the first video player 103 a is communicating. Preferably, the system first initiates the recovery sequence and only checks to see if the primary players is communicating after finding that the recovery sequence in unsuccessful. If the first video player 103 a is communicating, the system may switch back to the first video player 103 a. If not, the system may store a downtime event or failure data at the system control board 101 and optionally transmit the downtime event or failure data to the NOC device 200. In some embodiments, the system may perform both functions when the first video player 103 a is not communicating. Further, if both the first and second video players 103 a and 103 b are not communicating, the system may direct the display assembly 200 d to remain in a failure or downtime event condition. For example, but without limitation, the failure or downtime event condition may display a default or error message.

FIG. 5 is a logical flowchart for operating a fourth embodiment of the system. Here the system begins by driving the display 30 from the primary player 103 a. The system would then check to determine if the primary player 103 a is communicating. If so, the system continues normal operations with the primary player 103 a. If not, the secondary player 103 b would then be used to drive the display 30 and the system may force a power off of the primary player 103 a and then initiate a recovery sequence on the primary player 103 a. The system would then return to check if the primary player 103 a is communicating. If so, the system resumes operations from the primary player 103 a, using it to drive the display 30. If not, the system continues operations with the secondary player 103 b and may store a downtime event or failure data at the system control board 101 and optionally may transmit the downtime event or failure data to the NOC device 200.

FIG. 6 is a logical flowchart for operating a fifth embodiment of the system. In this embodiment, the system begins by pinging an outside server or internal network address that is known (or assumed) to be operational. If there is no response from the ping, a downtime event is stored for the network connection, indicating some type of failure within the network and/or the network interface component 70. The system may then return to ping an outside server or internal network address that is known (or assumed) to be operational. If there is again no response, then a downtime event is again stored for the network connection. Once the system receives a response for the ping, it may optionally transmit one or all of the downtime events to the NOC device 200.

FIG. 7 is a logical flowchart for operating a sixth embodiment of the system. In this embodiment, the system begins by pinging an outside server or internal network address that is known (or assumed) to be operational. If there is a response to the ping, the system may return to re-ping an outside server or internal network address again in the future to confirm that the network is operating correctly. If there is no response from the ping, the system may initiate a recovery sequence of the network interface component 70. The system would preferably return again to re-ping an outside server or internal network address again in the future to confirm that the network is operating correctly.

FIG. 8 is a logical flowchart for operating a seventh embodiment of the system. In this embodiment, the system control board 101 may analyze each frame of video/image data from the video player 103 a to determine if the frame data has changed over a period of time (T), which can be any period of time chosen by the user, where an exemplary period of time (T) may be on the order of 10-15 minutes, but again could be any period of time. If the frame data has changed, the system would return to have the control board 101 analyze more frames of video/image data. If the frame data has not changed over T, then a default image or video may be displayed while the system initiates a recovery sequence on the video player 103 a. Optionally, the system may store a downtime event or failure data for the video player 103 a at the system board 101. After running the recovery sequence on the video player 103 a, the system may return to normal operations so that the control board 101 may analyze more frames of video/image data to confirm that either the video player 103 a is now operating properly, continues to operate properly, or continues to have downtime or a failure.

FIG. 9 is a logical flowchart for operating an eighth embodiment of the system. Specifically, FIG. 9 describes an exemplary embodiment of the recovery sequence. The recovery sequence may include a simulation of the user depressing the power button 104 a and/or attaching and reattaching the power supply (i.e., unplugging and re-plugging in the display assembly 200 or individual components thereof). The recovery sequence may comprise a simulated “short push” of the power button 104 a, a “long push” of the power button 104 a, and/or ceasing to supply power to the video player 103 a and then reapplying power after a period of time has elapsed. The short push may simply command the video player 103 a to restart. The long push may force the video player 103 a to restart. Alternatively, or in addition, the recovery sequence may cut power to the video player 103 and then reapply power after a period of time has elapsed.

In exemplary embodiments of the present invention, the system may first simulate a short push of the power button 104 a for the video player 103 a and allow time for it to restart. The system may then check to see if the video player 103 a is communicating. If so, the system may store a downtime event and optionally may transmit the downtime event to the network operations center 200. If not, the system may simulate a long push of the power button 104 a and allow time for the video player 103 a to reboot. The system may then check to see if the video player 103 a is communicating. If so, the system may store a downtime event and optionally may transmit the downtime event to the network operations center 200. If not, the system may cease applying power to the video player 103 a, wait a predetermined amount of time, and reapply power to the video player.

Optionally, the system may then check to see if the video player 103 a is communicating. If so, the system may store a downtime event and optionally may transmit the downtime event to the network operations center 200. If not, the system may store a failure, optionally place the display assembly 200 d in a default or failure mode, and optionally may transmit the failure to the network operations center 200.

While the recovery sequence is discussed with respect to the video player 103 a and the respective power button 104 a, it may be utilized with the second video player 103 b and the respective power button 104 b, the power button 75, as well as with other components of the system.

As used herein, a downtime event and/or failure is a data package representing any number of pieces of data including but not limited to the date and time for when the particular portion of the system went down, specifically which component of the system went down, how long the component was down, and the date and time for when operations resumed.

In exemplary embodiments of the present invention, and as discussed herein, the first video player 103 a may be designated as the primary player, and the second video player 103 b may be designated as the secondary player, though the reverse is contemplated.

The electronic display 30 can be any flat panel electronic display including but not limited to: liquid crystal displays (LCD), organic light emitting diode (OLED) displays, plasma displays, electroluminescent polymer displays, and the like.

Those having an ordinary level of skill in the arts will recognize that the buttons described herein, such as but not limited to the power button 75 and the power button 104, may be physical buttons or may be non-physical buttons such as an electrical signal, switch, circuit, transistor, or the like.

Having shown and described a preferred embodiment of the invention, those skilled in the art will realize that many variations and modifications may be made to affect the described invention and still be within the scope of the claimed invention. Additionally, many of the elements indicated above may be altered or replaced by different elements which will provide the same result and fall within the spirit of the claimed invention.
